well, in the style of shito ryu that I practice, Minami Hankyo Shito-Ryu, it´s mostly motodachi, neko ashi, and shiko dachi... the feet movement when u walk in shorin are in a straight line, in shito as in shoto and goju, you walk doing a circular movement with your feet... The timing of the kata is probably as fast as shorin ones... hope I helped...
